Fast Co: Huge Underground Farm Hiding Beneath London’s Streets

What a brilliant idea! Grow underground – plenty of space and weather is not an issue…

FC: The newest branch line of the London Underground doesn’t go anywhere. But it does produce a lot of nice food to eat. It’s an aquaponic hydroponic farm, 100 feet below the surface, set to open this March.

The 2.5 acre project relies on its location in a tunnel to reduce heating and cooling costs. The temperature stays stable at 60 degrees all year round. There aren’t many airborne pests to worry about either. A simple filter takes out any nasties, and lets the produce–which includes pea shoots, rocket, broccoli, mustard leaf and basil–grow without pesticides.
